BELT-FASTENEFL SPECIFICATION forming part of Letters Patent No. 398,857, dated March 5, 1889.

Application filed Jctoher 18, 1888. Serial No. 288,440. No model.)

To aZZ whom, it may concern: 7

Be it known that I, JAMES SNOW, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements 'in Belt-Fasteners; and I do hereby declare the following to be a'full, clear,

- and exact description of the invention, such as will enable others skilled in the art to which 3 thin points being also easily clinched, whereupon the rounded sides thereof are embedded in the belt without breaking the fiber of the latter and leaving the flatted sides of the teeth from the bend in clinching to the point flush with the surface of the belt, the object being to provide a cheap belt-fastener adapted,

by using more or less in number, to fasten any width of belt, leaving the belt when so fastened flexible crosswise, so that it may adapt itself to pulleys more or less crown'in In the accompanying drawings, Figures 1 and 2 are respectively side and end elevations. l igs. 3 and 4 are plan views showing different manners of applying the fastenen 3 Fig. 5 is an edge view of the belt in section, f

I belt runs over small pulleys, short fasteners,

showing the fasteners clinched.

A represents the body of the fastener, the

' same being a metal bar, preferably of malleable cast-iron, the bar having a flatted side face-that is, on the face opposite the other tooth-is cut away or fiatted, as shown at a, whereby what would otherwise be a round point, difficult to clinch, is converted into a thin cutting-edge, easily clinched, and as the points of the teeth are bent inward in clinchin g-th at is, toward each other-the rounded sides of the teeth are embedded in the belt, but by reason of the rounded surfaces do not break the fiber of the belt. The clinching brings the flattened side of the tooth from the bend to the point outside, and is flush with the surface of the belt, making a smooth surface therewith. Any number of these fasteners may be applied, more or less, according to the width of the belt, and, being narrow and entirely disconnected the one fastener from another, the belt remains flexible crosswise, and may therefore fit crowning pulleys at the splice with the same facility as other parts of the belt.

The fasteners are placed upon the belt astride the joints and the teeth are driven through the belt and clinched, (see Fig. 5,) the operation requiring but a few minutes time even for a wide belt. The base of the teeth being considerably larger than the cutting-point aforesaid, the fiber is pressed buck and packed around the tooth, making illlll contact with the latter, and as the draft on the tooth is against the ounded side thereof there is no liability of cutting or tearing the belt by ordinary workin strain.

Of course the fasteners are made of different sizes and different lengths of tooth, according to the thickl'icss of the bell.

The different methods of applying the fasteners are shown in Figs. 3 and 4:. here the i, are preferable.
